Create a new branch named _"vx.y.z-proposal"_, or something similar. Using `git cherry-pick`, bring the appropriate commits into your new branch. To determine the relevant commits, use [`branch-diff`](https://github.com/rvagg/branch-diff) and [`changelog-maker`](https://github.com/rvagg/changelog-maker/) (both are available on npm and should be installed globally). These tools depend on our commit metadata, as well as the `semver-minor` and `semver-major` GitHub labels. One drawback is that when the `PR-URL` metadata is accidentally omitted from a commit, the commit will show up because it's unsure if it's a duplicate or not.

Carefully review the list of commits looking for errors (incorrect `PR-URL`, incorrect semver, etc.). Commits labeled as semver minor or semver major should only be cherry-picked when appropriate for the type of release being made. Previous release commits and version bumps do not need to be cherry-picked.
